Brrrr. Another Cold Night in Johnston Could Freeze Plants

If your plants survived the early morning hours without a blanket, don’t be so cavalier heading into the nighttime hours Tuesday.

The National Weather Service says central Iowans can expect another cold night Tuesday with temperatures at or near freezing and patchy frost after 3 a.m.
